Menstruation is a normal physiological phenomenon in women, and its regular cycle rhythm is regulated by the hypothalamic-pituitary-ovarian gonadal axis. A few days before menstruation, due to hormonal fluctuations in the body, there may be easy fatigue, edema of the hands, feet and eyelids, headache, breast pain, pelvic pain and other pain, as well as anxiety, depression, impatience, irritability, mental tension and other physical and mental symptoms, called “premenstrual tension syndrome. In the menstrual period, due to pelvic congestion, dizziness and weakness, lumbar swelling, lower abdominal cramps and other discomfort, dysmenorrhea may be accompanied by nausea, vomiting, pale, cold sweat, and even fainting. Girls in adolescence, for menstruation brought about by the sensitivity, tension, emotional instability and the emergence of physical symptoms, easy to lead to slow reactions, learning efficiency, which more or less have an impact on the normal performance of the level of college entrance exams. Therefore, how can smoothly through the period of high school menstruation, is the majority of high school girls and parents are particularly concerned about the issue. 1, avoid periods Due to psychological and physical changes, menstrual discomfort may affect the normal performance of the college entrance exams, many girls ask to adjust the menstrual cycle. Generally speaking, there are two ways to change the menstrual cycle: (1) advance method: in the middle of the menstrual cycle, that is, the 15th day of the menstrual cycle started daily oral progesterone capsules or intramuscular progesterone, for 5 days, 3-7 days after stopping the drug menstruation. This method can be used by girls with PMS. (2) Postponement method: Girls without PMS can postpone the onset of menstruation by taking oral contraceptives from the 5th day of the menstrual cycle, taking one tablet orally at bedtime every day until the end of the entrance examination, and then stopping the medication and having menstruation; or taking progesterone capsules orally every day from the middle of the menstrual cycle until the end of the entrance examination, and then stopping the medication and having menstruation. This method is sometimes unreliable. It should be emphasized that artificial adjustment of the menstrual cycle is not in accordance with the physiological mechanism of the human body and should be avoided as much as possible. For girls who do need to adjust their menstrual cycle, they should always use the medication under the guidance of a gynecologist, and should not take the medication on their own or use it in excessive doses to avoid lifelong regrets. Adjustment of the menstrual cycle can be done two months in advance, and if the menstrual period is not in the ideal time range, it can be adjusted again in the next month. 2, reduce pain Some girls are especially afraid of having their periods during the entrance exams because of dysmenorrhea, which affects the normal performance of the exams and thus causes great psychological pressure. The first thing is to pay attention to rest, adjust their work and rest time; the second in the diet to eat easy to digest and absorb food, avoid cold food, a glass of hot milk before bed, but also to relieve the pain of the effect. At the same time, under the guidance of gynecologists, the appropriate use of long-acting slow-release analgesics, such as ibuprofen, ketoprofen, etc.. When dysmenorrhea begins, take painkillers, generally painkillers will take effect after 20-30 minutes and last 12 hours without pain, repeat the medication if necessary. 3, adjust the mentality For girls before the college entrance examination, it is important to adjust their mentality before the examination, combined with the special physiological needs of the premenstrual period, regular rest and rest time, adequate sleep and rest, reasonable diet with appropriate symptomatic treatment, establish self-confidence, and smoothly through the college entrance examination period.

There is no need to deliberately disrupt the menstrual cycle if there is usually no discomfort during menstruation, no dysmenorrhea, etc. The drugs used to regulate the menstrual cycle are hormonal and have side effects such as breast pain, nausea, vomiting or nerve disorders, which can have psychological and physiological effects on the candidate. For those with poor psychological quality, it will be detrimental to the performance of the examination. In addition, two days before the onset of the period to carry out appropriate exercise, can promote blood circulation, is conducive to the discomfort through the period.
